3D Dungeon Generator vs L3DT

3D Dungeon Generator makes procedural, solvable room-and-corridor dungeons in a browser. It places rooms without overlap and connects them with carved corridors; users can adjust room count, room size, and corridor width. A seed and its settings can reproduce the same layout, including a route from entrance to exit, with optional extra corridor links. The real-time preview supports orbiting, a top view, fit controls, and first-person walking from the entrance. Themes include Stone, Backrooms, Dungeon, Concrete, Sci-Fi, and Hedge, and users can supply wall, floor, and ceiling textures. GLB export includes the dungeon geometry and current materials, with options for a ceiling and solution path. Custom texture support in exported GLB depends on browser image decoding. The tool is free at free, browser-based, and requires no signup or subscription. Dungeon sizes range from 16×16 presets to custom dimensions up to 60×60. LevelRift Labs lists uses such as game level prototyping, game jams, dungeon concepts, and Blender or other GLB-compatible workflows. The product page says original texture files are not uploaded by the app.

L3DT is a terrain-generation and editing application for game developers and digital artists creating large 3D worlds. Its design map lets users define terrain characteristics and effects such as altitude, roughness, lakes, climate, erosion, terraces, cliffs, and volcanoes. A 3D heightfield editor provides mouse-driven brush tools. L3DT generates ground textures, alpha maps, and light maps, including shadow casting and bump mapping. The free Standard Edition supports heightfields and texture maps up to 2049 × 2049 pixels. Professional editions support larger maps through disk paging: heightfields up to 131,072 × 131,072 pixels and textures up to 4M × 4M pixels. Professional Indie costs $34.95, paid once; Professional Commercial costs $149.95, paid once. Both include two years of free upgrades. Formats include BMP, JPG, PNG, TGA, DDS, OBJ, COLLADA, Terragen TER, and Virtual Terrain Project BT, with GeoTIFF import. L3DT supports plugins, custom filters, and Python and ZeoScript scripting through plugins. It is a Windows application; Linux use through Wine is recommended for testing because bugs may occur.
